Thermax Babcock & Wilcox Energy Solutions

Range :

Capacity: 1000 TPH to 3175 TPH
Pressure: Subcritical
SH and RH Temperature: Up to 585°C

Benefits:

B&W has extensive worldwide experience in designing, manufacturing, installing and servicing more than 700 Radiant Boilers up to 900 MW.

B&W’s Radiant Boilers, Carolina Type (RBC) and El Paso Type (RBE) incorporate natural circulation which takes advantage of the density difference between water in the down-comers and the steam/water mixture in the furnace tubes to provide cooling flow in these tubes. With natural circulation, no pumps are required, so auxiliary power requirements are reduced and availability is improved.

The RBC is designed to fire pulverized coal. The RBE is designed to fire natural gas and/or oil, blast furnace gas and combustible by-product gases.

Range :

Capacity: No lower or upper limit, largest B&W PGG to date is 4535 TPH
Pressure: Supercritical
SH and RH Temperature: No upper limit, highest to date is 620°C

Benefits :

B&W has extensive worldwide experience in designing, manufacturing, installing and servicing more than 90 supercritical boilers.
B&W installed the first supercritical boiler in the world in 1957 and supplied the largest single unit boiler ever built (1300 MW). 9 such units have been installed by B&W to date.
A spiral furnace design provides better heat transfer and variable pressure operation.

B&W low NOx combustion systems offer an advanced design and rugged construction for proven performance and superior reliability. Our low NOx burner technology has been successfully applied to a broad range of units (more than 132,000 MW; over 9,000 burners) with varying fuel characteristics and boiler arrangements.
